WHIFFLETREE.

SPECIFICATION forming part of Letters Patent No. 772,233, dated October11, 1904.

\ Application filed June '7, 1901. Serial No. 63,629. (No model.)

To all whom, it may concern.-

Be'it known that I, J AMES HAIR, a subject of the King of Great Britain,residing in Tyne street, Oamaru, New Zealand, have invented new anduseful Improvements in Whiffletrees, of which the following is aspecification.

This invention relates to improvements in whifiietrees, and has for itsobject to provide improved means for attaching and locking the traces tothe ends thereof.

According to the invention each end of the whiflietree is provided witha sliding pin, having a spring by means of which it is normally causedto project from the end of the whiffletree, and in conjunction with thesaid pin there is arranged a bracket or eye, preferably of metal, havinga hole or bearing into which the end of the aforesaid pin enters whenheld in its outermost position under the action of the spring. Athumb-piece or the like is fitted to the pin to enable it to bewithdrawn from the bearing or hole in the eye when desired to attach ordetach a trace end.

In the accompanying drawings, Figure 1 is a side elevation of awhiflletree end having the improved attachment applied thereto. Fig. 2is an end elevation showing the trace-eye attached, and Fig. 3 is alongitudinal sectional elevation of the whifiietree end and attachment.

(0 is the end of'the whiffletree, the said end being tapered andprovided with a metal socket b, suitably secured thereto-for exam: ple,by the screw 0.

d is the sliding pin, which is held in a central recess or socket e inthe end of the whiffi'etree, and f is the spring by means of which itnormally caused to project from the said g is the bracket or eye, whichis formed of metal and is secured to the end of the metal socket I; attwo difierent points, said bracket being provided at its front end withthe hole or bearing h, into which the end of the pin d enters whenpressed outward under the action of the spring.

71 is the thumb-piece, which has a stem j engaging a slot is in thesocket b and whiflietree end a and secured to the sliding pin (Z. Bymeans of this thumb-piece the said pin can be withdrawn into thewhiffletree end against the action of the spring f. A guard Z isprovided on the thumb-piece to cover the slot in the whiffletree endwhen the pinisin' its outermost position, as clearly shown in thedrawings.

made in one piece, as clearly shown in the drawings.

With this arrangement to attach a trace to the whiffletree the pin (1 iswithdrawn from the hole It in'the bracket g against the action of thespring f. The link or eye m, Fig. 2,

at the end of the'trace is then placed within the bracket g and thethumb-piece 2' released, so as to allow the pin d to spring outwardthrough the trace-eye m and into the hole or bearing ii in the bracketg, thus securely attaching the trace to the whiffletree. To detach thetrace, it will obviously only be necessary to withdraw the pin d againstthe action of the spring f by means of the thumbpiece z'.

Having now particularly described and ascertained the nature of my saidinvention and JAMES HAIR. Witnesses: I
